DISHWASHER.

Application filed February 10, 1926. Serial No. 87,222.

Our invention relates particularly to dish Washers.

The main object of our invention is to provide a convenient liquid mixeradapted to be connected to water pipes or to other sources of liquidsunder pressure. Another object is to provide convenient means for thewashing of any articles which may be cleaned by the application ofliquids, .for example, the washing of dishes with a mixture of Water andliquid soap. Another object is toprovide convenient means for temperingwater and mixing soap with it when desired.

The preferred form of our invention comprises a rigid container having aflexible receptacle Within it. entrance of a liquid under pressurewithin the container to compress the inner receptacle. Both thecontainer and the receptacle are adapted to discharge into a commonchamber which is formed so as to accelerate the mixing of the liquids.

Fig. 1 is a front view of one form of a liquid mixer embodying ourinvention.

Fig. 2 is a plan view of the liquid mixer shown in Fig, 1. v

Fig. 3 is an end view of the same liquid mixer. I

Fig. 4 is a partly sectional View of the preferred form of liquid mixerembodying ourinvention. This form may be quickly attached to or removedfrom the conventional hot and cold water faucets. I

Fig. 5 is a side view of the. form of liquid mixer shown in Fig. 4.

Fig. 6 1s a plan view of a detail. Fig. 7 1s a sectlonal View of thesame. The container 10 may be made of anyrigid material suitable forholding Water or other liquids under pressure. It is connected tosources of liquid supply such as faucets 11 and 12, by pipe sections 13and 14 and has an outlet member 15 and a flexible discharge pipe or hose16 to provide means for discharging the liquids under pressure and fordirecting a jet or spray against the surfaces to be cleaned or sprayedin any suitable man ner. The container has a cover 17 adapted to besecured to the container in an air tight manner by screws 18.

The cover has an inlet opening for soap closed by a cap 19. Fig. 4 showsa slightly different arrangement of faucets 11 and 12. WVithin thecontainer 10 is a flexible bag or Provision is made for the.

receptacle 20, for instance, of soft rubber adaptable for holdingfluids. This receptacle restson a perforated platform 21 havingsupporting lugs 22 so that water pressure can be applied. The rim of thereceptacle is compressed between the container 10 and the cover 17. Thisarrangement forms an air-tight seal between the container and its coverand at the same time holds the flexible receptacle in the position shownin Fig. 4.

The receptacle 20 has a discharge member 23 having a control valvemember 24. The discharge member 23 is smaller than the discharge outlet15 and is designed to occupy a position Within it substantially as shownin Fig. 4. The outlet 23 may be secured to the bottom, of the receptacle20 by a nut 25. V

The member 23 and its valve 24 constitute in effect parts of the outletmember. A pipe section 26' connected to the reservoir 10 is connected toa socket member 27 in an extensible manner. A soft rubber bushing member28 is adapted to fit over the end of the faucet 11 in a water tightmanner. The connection to the faucet 12 is effected in the same manner,so that'the'apparatuscan be readily attached to any ordinary pair of hotand cold Water faucets.

In operation, the flexible receptacle 20 is first filled with a suitableliquid such as soap.

' Then the faucets are opened to provide hot or cold water in theproportion desired. The water (or 'otherliquid) coming into thecontainerflows'out of the discharge member 15 and at the same timeexerts a pressure against the sides of the flexible receptacle 20 andforces out the soap in a quantity which may be regulated, by the valvemember 24.

Theliquids readily mix in the tapered section of the discharge member 15and flow out of the hose 16 to be discharged against the articles to becleaned or sprayed.

Any suitable form of discharge nozzle with or without a brush such as 30may be employed. I i

The discharge pipe 16 in Figs. 1, 2 and 3 is shown as swivelled so thatit can beturned into the various positions shown. In the form shown inFig. 4 the flexible hose 16 is dletachable and the brush 30 is alsodetacha le.

This liquid mixer has proven itself to be very convenient andserviceable in the washing of dishes and other household utensils.
